Charging MSR/MCX/9958's 1 Cell Battery one by one is time consuming and also a trouble task, isn't it? Here you can charge three 1-Cell Battery at once using an external Balance Charger (eg. RCX B3 2-3S Li-Polymer Charger).

Usage Example:

But beware that you need a good balance charger, the best one should be a single processor monitoring each single battery cell, so it will stop charging when a particular cell is full. Bad balance charger may damage the battery.

The Red JST Male connector will then become a 2S Battery. This JST connector is used by some chargers required to discharge the battery during balancing such as iMax B6.
